If you have children between the ages of 3 and 11, there's an app you have to get: Tales2Go. It provides on-demand access to more than 1,000 children's audiobooks and stories--everything from "Diary of a Wimpy Kid" to "Junie B. Jones."

The app is free, but a one-year subscription costs $24.99, which is a steal in my book.

However, if you download and register Tales2Go using a valid e-mail address between now and midnight tonight (Pacific Time), you'll get a summer's worth of streaming absolutely free.

Specifically, instead of expiring after 30 days--the standard trial period--Tales2Go will keep on playing through Labor Day.

After that, you'll need to pony up your $25 if you want more streaming goodness. As I mentioned, I think that's a tremendous deal, especially considering that a single audiobook CD can easily cost that much.

Of course, you have nearly three months to decide that for yourself. Just make sure you grab the app and register it today. As of 12:01 a.m. Saturday, the deal is over.
